Question

Butane is used as a fuel in camping gas stoves.100 cm3 of butane is burned in excess oxygen .calculate the volume of carbon dioxide produced at r.t.p

Answer 1

The given for the problem:

100 cm^3 butane

Get first the molecular formula of butane and it is C4H10

To solution for the problem is:

2 C4H10 + 13 O2 = 8 CO2 + 10 H2O
n = V/22.4

n (C4H10) = 0.1/22.4 = 0.0047 mol

n (CO2) = 4 · n (C4H10) = 4 · 0.0047 = 0.018 mol
